Abstract: An emulsion composition and a method for preparing the emulsion composition are disclosed. The emulsion composition contains an inner phase; an external phase; and a plurality of interfacial particles surrounding the surface of the inner phase to form an interface, wherein the interfacial particles have a particle size smaller than the inner phase, and the interfacial particles include organic particles. The method for preparing the emulsion composition includes steps of: preparing a colloidal solution comprising a dispersion medium and organic particles dispersed in the dispersion medium; preparing an aqueous phase; preparing an oil phase; and mixing the colloidal solution, the aqueous phase, and the oil phase so as to prepare the emulsion composition.

Abstract: The present specification describes an additive composition for preventing the precipitation of vitamin C in a cosmetic composition containing 15 wt % or more of vitamin C. The additive composition of the present invention comprises one or more of 3-O-ethyl ascorbic acid and caffeine as an active ingredient, and can thereby prevent precipitation of vitamin C even when a cosmetic composition is in cold storage. In addition, the additive composition according to the present invention can ameliorate the tingling irritation and stickiness that results from the inclusion of a high content of vitamin C.

Abstract: Nanocapsules that form emulsion particles and an emulsion composition including the nanocapsules are disclosed. The emulsion composition contains an aqueous phase; an oil phase; and emulsion particles surrounded by a plurality of non-amphiphilic nanocapsules located in the interface between the aqueous phase and the oil phase. The emulsion composition is capable of forming emulsion particles in an oil-in-water-type emulsion composition, without using a surfactant.
